I still have a very well operating XP laptop and all XP apps running very well on it...But I would be very ill-adviced to use it with current security software loaded, with current apps and online.
I also have older Win-7 computers, again all XP and Win-7 programs run perfectly on it, but I use it offline for those programs only - if I happen to have the time and I want to run some 'exclusive' apps that don't run on modern machines with Win 10, Win 11.
Take your Win-7 machine, remove all ridiculous obsolete security software from it, and run it offline only. Use a modern machine for newer apps and online activity.

P.S:
Now I remember, I still have an old Amiga computer from pre-1990, runs perfectly but I hardly use this one because I have emulation sofware en-masse for Amiga programs...
Oh, and I still have the first 'speaking' chess computer too, from 1976 I believe, true original synthetized voice technology...Without securtiy software...It has taken a lot of dust since, so his 'voice' is a bit on the modern rapper style...
